A decent bathroom need not be overly-luxurious like those of emperors. However, it should be big enough and contain all the necessary essentials such as a soap, shampoo, lotions and scents.

The bathroom is probably the next most important room after the bedroom. We need to spend time in the bathroom to clean ourselves before leaving the house or even at night when we had arrived home after a day's work outside. Bathrooms should be large enough to be comfortable for us to move around and allow us to do our daily activities such as showering or shaving. Some bathrooms are luxurious enough to contain a bath tub for the ultimate luxury while bathing. Others include sinks as well.
Essentials in a bathroom include mirrors, cabinets, curtain rails, heated-towel rails, shower screens, shower cubicles and maybe even macerators. Included here are the glass bowls and wash stations essential during shaving and also brushing teeth. Other items needed can also be installed depending on individual preference and budget.

This site is dedicated exclusively to bathroom essentials. It is focused on bathtubs and bathroom sinks which are the main focal points of any decent bathroom. Sinks often are located outside a bathroom but it is better to have a sink inside a bathroom for obvious reasons. On the other hand, a bath tub offers the promise of a very luxurious prolonged bath, especially for women. However, one must be careful because bath tubs can be a source of danger and accidents as they are quite slippery when used.
